Rootless podman adguard home failing

I'm trying to get rootless podman to run adguard home on Debian 12. I run the docker-compose.yml file via podman-compose up -d.

I get errors that I cannot google successfully, sadly. I do occasionally see shards of people saying things like "I have adguard running with rootless podman" but never any guides. So tantalizing.

I have applied this change so rootless can yoink port 53:

sudo nano /etc/sysctl.conf

net.ipv4.ip_unprivileged_port_start=53 # at end, required for rootless podman to be able to do 53

(Do I even need that change with a macvlan?)

The sticking point seems to be the macvlan. I want a macvlan so I can host a PiHole as a redundant fallback on the same server. I error with:

Error: netavark: Netlink error: No such device (os error 19) and that error really gets me no where searching for it. I am berry sure the ethernet connection is named enp0s10 and spelled right in the docker-compose file, cause I copied and pasted it in.

I tried forcing the backend to "CNI" but probably did it wrong, it complained about:

WARN[0000] Failed to load cached network config: network dockervlan not found in CNI cache, falling back to loading network dockervlan from disk
WARN[0000] 1 error occurred:
        * plugin type="macvlan" failed (delete): cni plugin macvlan failed: Link not found

(I also made a /etc/cni/net.d/90-dockervlan.conflist file for cni but it didn't seem to see it and I couldn't muster how to get it to see it)

Both still occur if I pre-make the dockervlan with:

podman network create -d macvlan -o parent=enp0s10 --subnet 10.69.69.0/24 --gateway 10.69.69.1 --ip-range 10.69.69.69/32 dockervlan

And adjust the compose file's networks: call to:

networks:
    dockervlan:
        external: true
        name: dockervlan

Has anyone succeeded at this or done something similar?

podman 4.3.1

podman-compose 1.0.6

Getting a newer podman-compose is pretty easy peasy, idk about newer podman if that's needed to fix this.
